Connecting a large language model (LLM) to production revealed several challenges beyond initial testing. Real-world user inputs, which were often incomplete or ambiguous, caused the LLM's output to break downstream applications, even when the responses seemed fluent to humans. Implementing schema validation with tools like pydantic helped ensure structured output, but business logic validation remained a separate concern. Retrieval-augmented generation (RAG) systems struggled with outdated or conflicting information, necessitating better metadata management for documents. Furthermore, LLM tool-calling capabilities amplified errors, turning wrong answers into harmful actions, which was mitigated by limiting tool scope, validating arguments externally, and requiring confirmations for critical operations.
